The most significant one is a lack of tutorials/information on a lot of things, so I had to go on the internet and search. Such as customization options, instead of having a UI, I have to dig into the .env or docker_compose.yml to find certain options

Other differences include:

1. no edge functions: I don't see it in the UI, and I've tried to search how to set it up in a self-hosted Supabase, but no results
2. no logs/reports/SQL snippets: they also don't show up
3. no backup: it shows "Free Plan does not include project backups." but I am self-hosting

I haven't built anything on the hosted version, so I may be missing something that the hosted version has but the self-hosted one doesn't
